Dataset description

We demonstrate a Josephson junction with a weak link containing two ferromagnets, with perpendicular magnetic anisotropy and independent switching fields in which the critical current can be set by the mutual orientation of the two layers. Such pseudospin-valve Josephson junctions are a candidate cryogenic memory in an all superconducting computational scheme. Here, we use Pt/Co/Pt/CoB/Pt as the weak link of the junction with d_Co = 0.6 nm, d_CoB = 0.3 nm, and d_Pt = 5 nm and obtain a 60% change in the critical current for the two magnetization configurations of the pseudospin-valve. Ferromagnets with perpendicular magnetic anisotropy have advantages over magnetization in-plane systems which have been exclusively considered to this point. The magnetization and magnetic switching of layers in the junction does not affect the in-plane magnetic flux and so the maximum critical current is obtained at close to zero applied magnetic field, and the spin-orbit coupling in our system opens routes to additional device functionality such as spin-orbit torque switching of the barrier state.
